gogen's Issues

Local and remote sources

As generators can be built into a binary, it is crucial for them to have capability of loading local or remote resources. This should be done by creating "Importers". Importer is interface, that allows generator to retrieve resource that can be e.g. local file (resource.go) or remote gist, etc.

This will allow generators to be more flexible by creating layer, that is able to create resources not bound to the binary file.

Test generator

"As a programmer, I would like to generate test functions for my whole project"

This feature should allow programmers to auto-generate test files with all testing functions.

Segfault on parsing a field of slices of structs from another package

When parsing a structure that looks like this:

type Example struct {
	Readers []bytes.Reader
}

gogen panics. Output is this:

dao called
panic: interface conversion: ast.Expr is *ast.SelectorExpr, not *ast.Ident

Go Source importer

Source importer is a module, that allows to import structures, their function prototypes, constants, etc. from the single golang file. This will enable dynamic use of golang files, which provide context to the generator.

Segfault on parsing a method with reciever not yet defined

Gogen fails to parse files that have only methods in them. It is possible to store the definitions of types in some other file. Example:

package examples

func (r *MyModel) Add() {
  //some code
}

This will panic even if MyModel is defined in other file in the same package. Nil assertion should be added.

The specific line that panics is parse.go:124 .
